12V should be present for the headphone jack to working. I agree with xsq, check the sliders first.
I've known caps to cause similar problems as well, so might be worth checking those. You shouldn't need to change them all, but if you're going to change some (and they haven't been changing already) you may as well do all of them.

You shouldn't have done any damage to the board by connecting it up to a straight JAMMA harness, but it wouldn't sound good coming out of the speakers (one of the channels would be missing (right, IIRC)). Have you tried connecting it back up to a proper MVS harness?
Also, were you getting sound from the headphone jack before or was it always off the PCB edge?

Just don't use contact cleaner, it can damage them... that's why I said fader lube. If you don't have any, give it them a blast with some compressed air. But even if they are dirty you should have a crackling sound when you move them.
yes, the 2F is stereo only (MVS pinout on the edge). Connecting it via Jamma for a short time should not damage the audio section, but the longer you have it wired up wrong the higher the possibility it will go...

If the headphones jack gives audio but the JAMMA edge does not, then the problem is the amplifier circuit. The headphone audio goes unamplified, that's why the 5V mod works with these boards even when the amplifier needs 12V to work. Xian Xi explained that in another thread.
